New video focuses on Alaska’s acidifying oceans
Ocean acidification is how scientists describe the lowering of the oceans’ pH. The oceans today are roughly 30 percent more acidic than they were during the Industrial Revolution some 300 years ago. The rise in ocean acidification (OA) is tied to higher levels of carbon dioxide being released into the atmosphere by fossil fuel burning…
Read MoreAlaska Sea Grant State Fellowship alumnae move forward in their careers and education
Alaska Sea Grant’s State Fellowships are a career-building program modeled after the highly successful Knauss Marine Policy Fellowship. The fellowships provide an opportunity to acquire on-the-job experience in marine resource policies and programs in Alaska and they are geared toward soon-to-graduate or recently finished graduate students interested in marine policy and science. Since 2015, 11…
Read MoreCan mushrooms replace Styrofoam and keep the oceans cleaner?
A University of Alaska Anchorage researcher who hopes to curb ocean pollution thinks fungi might have a useful role to play. Philippe Amstislavski, an associate professor of public health at UAA, is experimenting with using mushrooms to create biodegradable insulation, shipping material and other environmentally friendly products. Alaska Sea Grant, a partnership between the National…
Read MoreSoutheast Alaska tribal council develops climate change plan
Climate change in Alaska’s high Arctic often captures headlines. Images of vanishing sea ice, dead seabirds, beached marine mammals, melting permafrost and houses tumbling into the ocean are common. Less media attention is directed to Southeast Alaska, an archipelago of hundreds of islands around a thin strip of mainland, blanketed by coastal temperate rainforest. But…
Read MoreSheffield, Ahmasuk honored for seabird mortality response
The U.S. Fish and Wildlife Service has honored Alaska Sea Grant’s Gay Sheffield and Brandon Ahmasuk of Kawerak, Inc. for leading a coordinated response to seabird mortality events across the Bering and Chukchi region. Since 2013, Sheffield, an associate professor at the University of Alaska Fairbanks, College of Fisheries and Ocean Sciences, and Ahmasuk have…

Blue Evolution is collaborating with the University of Alaska and Alaska Sea Grant on seaweed research aimed at developing cost-effective cultivation methods for several native species.
Read MoreScientists study fate of salmon in a changing Alaska landscape
From coastal shores to inland mountains, salmon are part of the fabric of Alaska. Salmon have been harvested by Alaska Natives for thousands of years and remain a critical part of the state’s commercial, recreational and subsistence fisheries. As anadromous fish, salmon spend the first months to years of their lives in freshwater before migrating…
Read MoreCarbon dioxide sample from Utqiaġvik provides wake-up call on climate
How does the buildup of carbon dioxide in the atmosphere measured at Hawai‘i’s Mauna Loa volcano over the last six decades compare with the air above Alaska? During a recent spring trip to Utqiaġvik, I had a chance to find out by visiting the farthest-north atmospheric observatory operated by the National Oceanic and Atmospheric Administration…
Read MoreAn interview with Alaska Sea Grant-funded graduate student Ashley Rossin
The Alaska Ocean Acidification Network recently profiled Ashley Rossin on her research interests, her Alaska Sea Grant research project looking at the effects of ocean acidification on clams, and her advice for other young scientists interested in the field.
Read MoreLaying the foundation for resilient coastal communities
Average temperatures in Alaska have increased twice as fast as anywhere in the country over the last century. This warming—as much as 6 degrees in winter and three degrees in summer—is expected to continue along with the effects of disappearing sea ice, thawing of permafrost, changes in fish and wildlife patterns, extreme flooding and erosion.…
